<div class="markdown_content"><p>I saw that using the -Y option won't result in a<br /> working parser in python. The problem appears to be the<br /> nature of the yyparser() function jumping back and<br /> forth, and of the way an yyerror macro is supposed to<br /> work. Nice to see these problems can be overcome in<br /> perl, where at least you can name loops.</p> <p>In python, you'll need some more trickery. The<br /> attached file demonstrates a possible approach.</p> <p>One more thing you need to know: the function below<br /> assigns to a local variable. When the function<br /> returns, the local variable is discarded:<br /> def yyclearin():<br /> yychar = -1<br /> In python, all lvariables that you assign to are local,<br /> unless<br /> explicitely state otherwise. It should be like this:<br /> def yyclearin():<br /> global yychar<br /> yychar = -1</p></div>
